What the option chain shows
GIFT Nifty is trading at +0.312% (+71.65 points) in the pre-market window, signaling mild continuation from Thursday's strong close. The prior session saw Nifty climb 368.62 points (+1.629%) and Sensex surge 1502.86 points (+2.064%), marking a decisive rally that has set the tone for this final Friday of the October expiry cycle.
India VIX sits at 14.03, reflecting contained volatility despite the week's upward trajectory. With just three days to expiry on the Nifty side and six for Sensex, the positioning has become more concentrated—both indices now face expiry-week dynamics that can amplify intraday swings even when headline VIX appears calm.
Bias and readiness
The 5-day average daily move for Nifty stands at 336.83 points and 1106.08 points for Sensex. Thursday's moves exceeded these averages, suggesting sustained conviction rather than a one-day spike. This sets a higher floor for what traders should monitor intraday.
On the options chain, both OI support and resistance zones show Addition activity. At the support end, Nifty's 22500 strike and Sensex's 73000 strike are accumulating fresh long positioning, indicating buyers are layering in downside protection. Simultaneously, at resistance, Nifty's 24000 strike and Sensex's 75000 strike are also seeing Addition, not unwinding—a signal that call sellers are still building hedges ahead of expiry rather than taking profits.
Levels to watch
Chart-based pivots offer near-term reference levels. Nifty's support sits at 22737.7 with resistance at 23156.7, a 419-point band. Sensex support is marked at 73364.56 and resistance at 74798.47, spanning 1433 points. These ranges will matter more than usual given the compressed expiry window.
The setup reflects a market that has momentum but is not yet overextended. Buyers are hedging their longs with fresh OI at support strikes, and sellers are protecting upside with fresh OI at resistance strikes—a sign neither side is all-in. The GIFT Nifty gap-up and the prior session's strength suggest buyers retained control Thursday, but the options chain positioning indicates Friday will test how deep that conviction runs before expiry rolls over into November series.
